Av windowstructure embodyingY a preferred forni of the presentinventionis illustrated in Figs.` 1 to '1, inclusive, of the drawings, wherein it is generally indicated at II,4 and comprises a windowV frame I2, which is preferably but not necessarily of wooden construction,- and 'which includes a pair of side members or stiles .I3, ya bottom member or sill I4 a top member I5, and a plurality of horizontally pivoted outwardly movablev window `sections or sashes eachof which is generally indicated', as a unit, at I6. Each ofthe'rnovable window sections IB .o

sashes includes a horizontal top rail` I1, va horizontal'bottom rail I8, "a pair ofvertically extending side rails I9 and'zll, and a glass win-,

dow pane 2l mounted therein.

The operating mechanism for the movable `window sections is generally indicated at 22 inthe drawings, and comprises a mainhorizontallyextending operating rock shaft which extendsbetween the window stiles` I 3 immediately above the window sill I4as"shown in Figs. 2 and ,7, Each. end portion 2l of the main operating rock 'shaft enlarged fragmentary detail view,J

28 is rotatably Journaled in a bearing opening 25 which is provided in an oifset bearing section 26 of a supporting bracket or metal casting 21,

which is preferably a die castingof a light corrosion-resistant aluminum alloy. Each of the castings 21 includes an upright portion 28, in which the offset bearing section 26l is formed, and each of-these upright portions 28 is suitably attached, as by screws 29, to one -of the upright window stiles I3 on the inner side thereof (Figs. 6 and '1). Each of the castings 21.also includes a baseplate or portion 86 and each of these base portions 36 is suitably attached, as by screws 3|, to the window sill I4, on the upper surface of the latter. One of the castings 21 also' includes a pair of spaced upright bearing elements or bosses I2 which are formed integral with the base plate or portion 36 thereof. Each of these bearing elements or bosses 82 has a bearing opening 92 formed therein and an end portion I4 of a shaft 85 is rotatably journaled in each of the bearing openings 88 (Fig. 6). The shaft 85 has a worm 96 formed thereon and the worm 86 is disposed between the upright bearing bosses '82,

As shown in Figs. 4 and 6, the worm shaft I5 has an extension 31 formed therein and this extension 81 is lournaled in a bearing opening 88 Awhich is formed in a bearing block 88-which is l The'extension f mounted on the window sill I4. 81 has a socket 46 formed therein for the reception of the inner end portion of a hand crank A4I (Figs. 3 and 4) The worm 86 on the shaft 85 meshes with a segmental gear 42 which is fastened. in any suitable manner, as by welding 4I. upon and to the horizontal operating shaft 2l (Fig. 6). The segmental gear 42 is, in turn, fastened, as by rivet 44,- to a power arm or, if desired, the segmental gear 42 and the power arm 45 may be made integral with each other in the form of 'a die casting or the like.

The power arm 45 is pivotally connected, as at 46, to the lower end portion of a link 41, and

the link 41 is, in turn, pivotally connected at its'V upper end, as by a headed pin 48, to a main vertically slidable operating member or bar 49.

A power arm, similar to the power arm 45, is mounted on vthe other end portion of the main horizontal operating rock shaft 23 except that in this instance the power arm is fastened directly to and upon the main horizontal operating rock shaft 29 and the worm shaft 35-86 and segmental gear 42 are eliminated. Otherwise the parts of the operating -mechanism arranged at both sides of the window structure, including the link 41, main vertically slidable operating member or bar 49, and other parts which are to be described hereinafter, are similar. two substantially similar operating mechanisms arranged at opposite sides of the window structure will be described hereinafter.

Each of the lowermost window sections I6 has a supporting member 56 'attached thereto onthe irner side thereof and each of these lowermost supporting members 56 is pivotally connected. at its upper end, toa main vertically slidable operating bar 49 and the adjacent link 41 (Figs. 4 and 5). Each of the lowermost supporting members 56 is pivotally connected at its lower end, as by a headed pin 5I, to a supporting arm 52 and each of the lowermost supporting arms 52 is, in turn, pivotally mounted, as at 53, upon an adjustable supporting plate 54. As shown in detail in Fig. 6, one end portion of each of the adjustable supporting Hence, only one of the headed pin 48, between the l 3 of the drawings.

plates 54 is pivotally fastened, as by a screw 55, to the upright portion 28 oi' one of the castings 21, and the other end portion of each of the supporting plates 54 has an arcuate or curved slot 56 formed therein. Thel shank of a screw 51 extends through each slot 56 and is anchored in a threaded opening provided therefor in the upright portion 28 of the corresponding casting 21, the head of the screw 61 spanning the slotll (Fig. 6). The purpose and operation of this arrangement will be described hereinafter.

As shown in Fig, 5, each of the suporting members 56 includes an attaching arm or extension 58 which is attached, as by screws 58, to the side rail 26 of the corresponding window section I6 As shown in Figs. 3 and 4;, each of the middle or intermediate window sections I6 and each of the uppermost window sections I6 also has one of the supporting members 56 attached thereto and each of these middle and upper supporting members 56 is pivotally connected at its upper end, as by a headed pin 60, to one of the main vertically slidable operating bars 46. Similarly, each of the middle and upper supporting members 56 is pivotally connected at its lower end, as at 5I, to one of the supporting arms 52, and each of the middle and upper supporting arms 52 is, in turn, pivotally connected at its lower end,as at 58, to one of the adjustable supporting plates 54. However, eachof the middle and 4upper adjustable supporting plates 54, rather -than being adJustably mounted on the upward extension 28 of one of the castings 21, as are the lowermost adjustable supporting plates I4, is similarly adjustably mounted upon a supporting plate or bracket 62 which is' attached to one of the window stiles I8 on the inner side thereof by means of screws or the like 62. As shown in Fig.

' tending channel-shaped groove 65 formed therein`and a channel-shaped metal guideway or liner 66 is arranged in each of the grooves 55 and is fastened therein by means of suitable fastening elements. such as screws 61, which are anchored in the window stiles I3. As is also shown in Figs, 2 and 5, each of the vertically slidable main operating bars 48 is arranged in and is slidably guided for vertical movement in'one of the channel-shaped'metallic guideways or liners 66.

The operation of the window structure and operating mechanism therefor illustrated in Figs. 1 to '1, inclusive, and which has been described hereinbefore, is-as follows: When the movable window sections I6 are disposed in closed position the parts of the new window structure and operating mechanism therefor are disposed in the relative positions in which they are shown in Fig.

themovable window sections I6 into open position, as in Fig. 4, it is merely necessary for the operator to insert the end portion of the hand crank 4I into the socket 40 provided therefor in the .outer end portion of the worm shaft 95-36 and then rotate the worm shaft 35-86 in a counterclockwise direction, as seen from the right in Fig. 3; Rotation thus manually imparted to the worm shaft 35-86 acts, through the segmental gear 42, to rock the main operating rock shaft 22 and the power arms 45 thereon in a counterclockwise direction from the position in which However, in order to move --lfin Fig. 4. Rotation ,jx a* haft 35 and worm 36 thereon will act, through Nvthe segmental "ding rock shaft 23 in a clockwise direction, as

these parts are shown in Fig. 3 into the position in which the same parts are shown in Fig. 4.

This movement of the main operating rock shaft 23 and attached power arms 45 acts, through the links 41, to move the main operating slide bars 48 downwardly in the channel-shaped metal guideways 65. This downward slidable movement of the main vertically slidable operating bars 49 acts, through the supporting members 50 and their pivotal connections 48 and 66 with the slide bars 49, in cooperation with the supporting arms 52 and their pivotal connections 5I with the supporting members 50, to impart a combined sliding and swinging motion to the window section i6, thereby moving the window sections i6 into open position, as in Fig. 4. During this operation the supporting arms 52 pivot at their lower ends, as at 53, upon the adjustable supporting plates 54 by which the supporting arms 52 and the window sections I6 supported thereby are attached to the stiles i3 of the window frame i2.

When it is desired to close the movable window sections i6 this may be readily accomplished by rotating the hand crank 4I and the worm shaft .35 and worm 36 in the opposite direction, that is, in a clockwise direction as seen from the right thus imparted to the worm gear 42 to rock the main operat- 'seen in Fig. 4, and this motion of the rock shaft 23 will act, through the power arms 45 and the links 4l, to slide the main operating slide bars 49 upwardly in their channel-shaped metal guideways 65. Such upward movement of the main operating slide bars 49 will thereupon act, through the supporting members 50 and the supporting arms 5I to impart a combined sliding and swinging motion to the window sections I6 so as to move the movable window sections I6 back into closed position, as in Fig. 3.

In the use of the new window structure illustrated in Figs. 1 to 7, inclusive, and hereinbefore described, the channel-shaped metal guideways 65 serve to facilitate the sliding movement of the main vertically slidable operating bars 49 therein and to minimize the friction incidental to the movement of the said main operating slide bars 49 which results in ease and facility of movement of the movable window sections I6 and the operating mechanism therefor. In addition, the provision of the channel-shaped metal guideways 66 prevents binding of the main vertically slidable operating bars 49 in their guideways due to swelling and the contraction of the window stiles i3 in which the channel-shaped grooves 66 for the channel-shaped metal guideways 66 are formed, when the window frame I2 is made of wood, incidental to varying conditions of atmospheric temperature and humidity, since such swelling and contraction as may occur in the wooden window stiles i3 will not materially affect the channel-shaped metal guideways 66. In this manner one of the difiiculties heretofore experienced in the use of somewhat similar wooden `window structures and operating mechanisms therefor is eliminated.

When the window sections I6 and the operating mechanism therefor are assembled in the window frame i2 itis essential that the supporting arms 52 be properly centered and mounted relative to the main operating slide bars 49. and the pivotal connections 48 and 60 between the supporting members 50 and the main operating 6 slide bars 49 since otherwise a binding action might occur during the combined sliding and swinging 'movement of the movable window sections I6 into'and from open and closed positions.

In the practice of the present invention, if the pivotal mountings 53 for the links 52 should be somewhat off their proper centers when the parts are assembled, the pivotal mountings 53 for the links 52 may be readily brought to their proper centers by loosening the screws 51 (Fig. 6) and pivoting the adjustable supporting plates 54 upon their pivotal mountings 55. The thus adjusted supporting plates 54 and the pivotal mountings 53 for the supporting arms 52, which are supported thereby, may then be clamped in the desired adjusted and properly centered position by adjusting thescrews 1 in the slots 56 so that the heads of the screws 1 are disposed in bind- .ing engagement with the adjustable supporting plates 54.

It will thus further be seen from the foregoing description, considered in conjunction with the accompanying drawings, that the present invention provides a new and improved window structure, and operatingA mechanism therefor, having the novel features of construction hereinbefore described, and that the invention thus has the desirable advantages and characteristics, and ac'- complishes its intended objects, including those hereinbefore pointed out, and others Which'are inherent in the invention.
